Side-Channel Attacks on the McEliece and Niederreiter Public-Key Cryptosystems

R.M. Avanzi and S. Hoerder and D. Page and M. Tunstall

Abstract: Research within “post-quantum” cryptography has focused on development of schemes that resist quantum cryptanalysis. However, if such schemes are to be deployed, practical questions of efficiency and physical security should also be addressed; this is particularly important for embedded systems. To this end, we investigate issues relating to side-channel attack against the McEliece and Niederreiter public-key cryptosystems, for example improving those presented by [19], and novel countermeasures against such attack.
